Welcome to the Journey of Cloud Engineering

Most people say they want to “host a simple web application in the cloud.” But here’s the truth: There is no such thing as a simple production web app . Even the smallest website needs the right combination of compute, storage, networking, and availability design to work reliably. Let’s break down what a “simple web app” actually needs; and how cloud engineers think about architecture before clicking any deploy button. What Is a “Simple Web Application”? At a basic level, a web application usually includes: A frontend (what users see in the browser) A backend (logic and APIs) A database (where data is stored) On paper, it sounds easy. But in real-world cloud hosting, you also need: Networking Security controls Scaling logic Monitoring Availability planning This is where architecture matters more than tools. Compute: Where Your Application Runs Every web app needs compute. This is where: Your backend code runs APIs process requests Busi...

In the last article, we spoke about the three pillars of cloud computing: compute, memory, and storage . These are the raw building blocks that power every workload; from websites to AI models. But here’s the real question: If cloud providers give you raw servers, disks, and memory, why doesn’t everyone manage them directly? The answer lies in abstraction . Cloud providers don’t just rent hardware. They package infrastructure into layers of services that reduce complexity, speed up deployment, and shift operational responsibility. This is where IaaS, PaaS, and SaaS come into play. Understanding these models is essential before touching AWS, Azure, or GCP; because every cloud service fits somewhere in this spectrum. From Hardware to Cloud Services Traditionally, companies managed everything themselves: Physical servers Networking equipment Storage systems Operating systems Security patches Backup hardware Cloud providers changed this by virtualizing and abs...

  Cloud Computing Fundamentals: Understanding Compute, Storage, and Memory If you remove all the buzzwords, logos, and dashboards from cloud computing, what remains? At its core, every cloud system (whether it runs a website, a database, an ERP like Dynamics 365, a VR application, or an AI model) is built on just three fundamental building blocks : Compute. Memory. Storage. Understanding these three is the difference between someone who uses the cloud and someone who engineers it. Let me ask you something first: Have you ever wondered why an application runs fast in one environment and painfully slow in another; even though both are “in the cloud”? The answer almost always comes back to how compute, memory, and storage were chosen and configured. 1. Compute - The Brain of the Cloud Compute is the processing power of your system. It is what executes code, runs applications, processes API requests, performs calculations, and drives everything forward. When you select a ...

  Welcome to the Journey of Cloud Engineering Cloud Engineering is more than a technical role - it’s a journey of continuous learning, problem-solving, and real-world impact . From hosting simple web applications to managing enterprise platforms and immersive VR experiences, cloud engineers sit at the intersection of infrastructure, automation, security, and business outcomes. This blog marks the beginning of a practical, experience-driven series on becoming a Cloud and IT Specialist. Rather than focusing only on theory or certifications, this journey will explore how modern cloud services are actually used, administered, and automated in real environments. Let me start with a question for you: Have you ever wondered how applications scale seamlessly, data stays secure, and deployments happen with minimal downtime? If yes, welcome—you’re in the right place. Why Cloud Engineering Is a Career, Not Just a Skill Organizations today rely on cloud platforms to move faster, reduc...
